Shane Warne says Emily Scott is at a different stage of her life and this was the main reason why their three-month relationship could not stand the test of time.

He may have had numerous lovers but Australia's spin wizard is not interested in having more kids. The father of three recently told a Melbourne-based radio station that he and girlfriend Emily Scott broke up because she wanted to have children.

Warne had tweeted last month that he and Scott - a Playboy model -- had decided to go their separate ways. Speaking to MyMp's on Thursday, the 45-year-old former cricketer said that the actual reason for the split was that he was not ready to have a child with Scott - 15 years his junior.

"She's such a cool girl, she's beautiful and lovely and sexy and all those sorts of things. Unfortunately she's just at a different stage of her life," he said. Warne already has three children -- daughters Brooke, 17, and Summer, 12, and 14-year-old son Jackson --Â from his first marriage.

Sad day as @EmilyLScott & I have gone our separate ways. We will always remain great friends & will continue to support each other. ??

Warne and Scott dated for close to three months and were quite public in their display of affection. Both were active on Twitter and showered love on each other. The talk of bringing in a child into the world though put an end to what appeared to be a fairytale romance. (Also read: Shane Warne compares himself to Suit's on-screen womaniser)

While Warne may not beÂ a stranger to heartbreaks - he ended his previous relationship with actress Elizabeth Hurley because she reportedly wanted to marry him -- Scott too has had her share of break-ups. The gorgeous and immensely talented model, DJ and TV personality, married English singer Ritchie Neville in 2008. The holy union though lasted all of four months.
